I know that situations arrive in which you miss school. Because of this, I wanted to make it a little easier for you see what you have missed! Posted will be the weeks lessons and assignments.
*Reminder: These are not "class notes". You will still be responsible for learning the material and getting notes from someone in class!!!
Material Covered:
Monday: Continue with Chapter 3 Sections 3 and Begin Section 4
ORDER OF OPERATIONS
Summary: To help us remember the order of operations, we can use the mnemonic PEMDAS, which stands for:
Please Excuse My Dear Aunt Sally Parentheses, Exponents, Multiplication & Division, Addition & Subtraction
Note that although there are six words, they correspond to four rules.
Tuesday:Quiz on Chapter 3 Sections 1 and 2
Wednesday:Finish Chapter 3 Section 4
Letters in math are called variables. They can stand for different numbers at different times.
A mathematical sentence is called an expression. It can include numbers, variables, signs of operation, and symbols of inclusion.
Signs of operation tell you what to do to the sentence. The four operations are addition, subtraction, multiplication, and division.
Symbols of inclusion are parentheses ( ) and brackets [ ].
An important caution: Be very neat in your calculations. Many an algebra problem is missed because the student misread what he or she had written or did not "line up" the column correctly for subtraction or division. Always double check operations. You don't want to miss a problem because you added incorrectly.
Thurday: Chapter 3 Section 5 SOLVING FOR X
When you solve for x, you want to "isolate" the x on one side of the equal sign. To do this, use the opposite sign of the number you want to move and do the same thing to BOTH sides of the equation.
For example:
8x + 2 = 50
8x + 2 - 2 = 50 - 2
(Subtract 2 from both sides of the = sign)
8x = 48
(Divide by 8 to solve because that is opposite of multiplication)
x = 6 Friday: Chapter 3 Review
Friday: Enjoy the weekend... NO HOMEWORK !!!**
Reminder, next week we will have a test on Chapter 3, so it may be a good idea to review your notes and homework problems over the weekend
